The turbocharger bearing including Deep groove ball bearing, Cylindrical roller bearing, Duplex mounting angular contact ball bearing and the unit matched by angular contact ball bearing and four point contact ball bearing.
The former two mainly loaded radial load and latter two can load radial and axial load. ZYS turbocharger bearing have the properties of high limit turning speed, large load capacity and long service life.
For the higher turning speed and larger load capacity bearing, alloy steels cages with some special surface treatment can be used.
